To enable cache components in Next.js 16, set cacheComponents: true in next.config.ts. This activates Partial Prerendering, allowing static shells, cached data, and dynamic segments to coexist within a single page route.

The 'use cache' directive in Next.js caches specific server-rendered content. It can be applied at file, component, or function levels to cache expensive data fetches, utilizing cacheLife and cacheTag to control the caching behavior.

You can revalidate cached data in Next.js 16 using updateTag and revalidateTag semantics alongside cacheTag. These functions allow you to selectively invalidate cached entries when underlying data changes, ensuring selective freshness on data-heavy pages.

Yes, cache components is designed specifically for routes mixing static content, expensive data fetches, and user-specific data. It wraps dynamic user-specific data in Suspense boundaries while prerendering the static shell and caching shared data.

Use cache components for dashboards, blogs, and data-heavy pages requiring fast initial render with selective freshness. If your page mixes static content with expensive or user-specific data fetches, cache components provide optimized partial prerendering over standard rendering.
